ʻO nā hale Sandwich ka mea maʻamau i hana ʻia me ʻekolu papa o nā mea.ʻO nā ʻaoʻao luna a me lalo o ka mea hoʻohui sandwich he mau mea ikaika kiʻekiʻe a kiʻekiʻe-modulus, a ʻo ka papa waena he mea māmā māmā.ʻO ka hoʻolālā sandwich FRP he hui hou ia o nā mea hana a me nā mea māmā ʻē aʻe.Hoʻohana ʻia ka ʻōnaehana sandwich e hoʻomaikaʻi i ka hoʻohana pono ʻana i nā mea a hoʻemi i ke kaumaha o ka hale.ʻO ka lawe ʻana i nā ʻāpana beam-slab ma ke ʻano he laʻana, i ke kaʻina hana, pono e hoʻokō i nā koi o ka ikaika a me ka rigidity.ʻO nā hiʻohiʻona o ke aniani fiber reinforced plastics he ikaika kiʻekiʻe, haʻahaʻa ʻo Modulus.No laila, i ka wā e hoʻohana ʻia ai kahi mea aniani i hoʻoikaika ʻia e hana i nā kaola a me nā papa e hoʻokō ai i nā koi ikaika, ʻoi aku ka nui o ka deflection.Inā hoʻokumu ʻia ka hoʻolālā ma luna o ka deflection i ʻae ʻia, e ʻoi aku ka ikaika o ka ikaika, e hopena i ka ʻōpala.Ma ka hoʻohana wale ʻana i ka hoʻolālā ʻana o ka hana sandwich hiki ke hoʻoholo kūpono ʻia kēia kūʻē.ʻO kēia hoʻi ke kumu nui o ka hoʻomohala ʻana i ka hale sandwich.

Ma muli o ka ikaika kiʻekiʻe, ka paona māmā, ka rigidity kiʻekiʻe, ka pale ʻana i ka corrosion, ka insulation uila a me ka hoʻoili ʻana o ka microwave o ka ʻōnaehana sandwich FRP, ua hoʻohana nui ʻia i nā mokulele, missiles, spacecraft a me nā hiʻohiʻona, nā panela o ka hale i ka ʻoihana mokulele a me ka ʻoihana aerospace.E ho'ēmi i ke kaumaha o ka hale a hoʻomaikaʻi i ka hana hoʻohana.Ua hoʻohana nui ʻia ke aniani aniani fiber reinforced plastic sandwich panel i nā hale kukui o nā mea kanu ʻoihana, nā hale ākea ākea a me nā hale ʻōmaʻomaʻo ma nā wahi anu.Ma ke kahua o ka hana moku a me ka lawe ʻana, ua hoʻohana nui ʻia nā hale sandwich FRP i nā mea he nui i nā submarines FRP, nā minesweepers, a me nā yachts.ʻO nā alahaka hele wāwae FRP, nā alahaka alaloa, nā kaʻa a me nā kaʻaahi, a me nā mea ʻē aʻe i hoʻolālā ʻia a hana ʻia ma koʻu ʻāina a pau i ka FRP sandwich structure, e hoʻokō ana i nā koi he nui o ke kaumaha māmā, ikaika kiʻekiʻe, rigidity kiʻekiʻe, insulation wela a me ka mālama wela.I loko o ka uhi uila e koi ana i ka hoʻouna ʻana i ka microwave, ua lilo ka hale sandwich FRP i mea kūikawā ʻaʻole hiki ke hoʻohālikelike ʻia me nā mea ʻē aʻe.

Nā ʻano a me nā hiʻohiʻona o nā hale sandwich FRP

E like me nā ʻano ʻano like ʻole a me nā ʻano o nā mea kumu i hoʻohana ʻia i loko o ka ʻōnaehana sanwiti, ua hoʻokaʻawale ʻia ka ʻōnaehana sanwiti FRP i: ka hoʻokumu ʻana i ka sanwiti foam, ka honeycomb sandwich structure, trapezoidal plate sandwich structure, rectangular sandwich structure and circular sandwich structure.

(1) Hoʻohana ʻia ka ʻili i hoʻopaʻa ʻia i ka ʻili (panel) a me ka ʻūhā ma ke ʻano kumu.ʻO nā ʻāpana me ka ikaika liʻiliʻi a me nā koi hoʻokō thermal insulation kiʻekiʻe, e like me nā huelo mokulele, nā ducts ventilation insulation thermal a me nā template.

(2) Honeycomb sandwich structure Honeycomb sandwich structure hoʻohana i ke aniani fiber reinforced plastic sheet e like me ka ʻili, a me ka mea honeycomb (ka lole aniani meli, pepa meli pepa a i ʻole nā lole pulupulu ʻē aʻe a me ka waihona meli alumini, a me nā mea ʻē aʻe) ma ke ʻano kumu.ʻO ka honeycomb sandwich structure he māmā i ke kaumaha, kiʻekiʻe i ka ikaika a kiʻekiʻe i ka rigidity, a ua hoʻohana nui ʻia no nā ʻāpana kūkulu me nā ʻāpana nui a me nā koi ikaika kiʻekiʻe, e like me nā papa haʻahaʻa o nā alahaka FRP, nā hale spherical roof, radomes, reflective. nā ʻili, nā papahele kaʻa i hoʻoheheʻe ʻia a me nā hale pahu E kali.

(3) Trapezoidal and rectangular lead-action layer structure ʻO ka panel (ʻili) o kēia ʻano papa hana alakaʻi he pepa aniani i hoʻoikaika ʻia i ka palaki, a ʻo ka ʻāpana sanwiti he kīʻaha aniani i hoʻoikaika ʻia i ka plastic trapezoidal plate a i ʻole ka pā ʻehā.He kuhikuhi ikaika kēia ʻano hana sandwich a kūpono wale no nā pā pālahalaha ikaika, ʻaʻole no nā huahana me nā ʻano curved.

(4) Hoʻohana ʻia i ka ʻili i hoʻopaʻa ʻia i ka ʻili a me ke apo aniani i hoʻoikaika ʻia ma ke ʻano he papa kumu.ʻO nā hiʻohiʻona o kēia ʻano hana sandwich ʻo ia ka haʻahaʻa o ka hoʻohana ʻana i nā mea waiwai, ʻoi aku ka kiʻekiʻe o ka ikaika, a ʻaʻohe kuhikuhi ka ikaika o ka pā.ʻO ia ka ipu aniani alohilohi i hoʻopaʻa ʻia i ka pā hana sandwich plastic no ka kukui.
